To help developers protect their applications against possible misuse, we are introducing the faster and more accurate Moderation endpoint. This endpoint provides OpenAI API developers with free access to GPT-based classifiers that detect undesired content — an instance of using AI systems to assist with human supervision of these systems. We have also released both a technical paper describing our methodology and the dataset used for evaluation.

When given a text input, the Moderation endpoint assesses whether the content is sexual, hateful, violent, or promotes self-harm — content prohibited by our content policy. The endpoint has been trained to be quick, accurate, and to perform robustly across a range of applications. Importantly, this reduces the chances of products “saying” the wrong thing, even when deployed to users at-scale. As a consequence, AI can unlock benefits in sensitive settings, like education, where it could not otherwise be used with confidence.

The Moderation endpoint helps developers to benefit from our infrastructure investments. Rather than build and maintain their own classifiers—an extensive process, as we document in our paper—they can instead access accurate classifiers through a single API call.

As part of OpenAI’s commitment to making the AI ecosystem safer, we are providing this endpoint to allow free moderation of all OpenAI API-generated content. For instance, Inworld, an OpenAI API customer, uses the Moderation endpoint to help their AI-based virtual characters “stay on-script”. By leveraging OpenAI’s technology, Inworld can focus on their core product – creating memorable characters.

Additionally, we welcome the use of the endpoint to moderate content not generated with the OpenAI API. In one case, the company NGL – an anonymous messaging platform, with a focus on safety – uses the Moderation endpoint to detect hateful language and bullying in their application. NGL finds that these classifiers are capable of generalizing to the latest slang, allowing them to remain more-confident over time. Use of the Moderation endpoint to monitor non-API traffic is in private beta and will be subject to a fee. If you are interested, please reach out to us at support@openai.com.

Get started with the Moderation endpoint by checking out the documentation. More details of the training process and model performance are available in our paper. We have also released an evaluation dataset, featuring Common Crawl data labeled within these categories, which we hope will spur further research in this area.
